This handy strategy guide was created with the help of Shadiochao’s video guide on YouTube that shows exactly how to find each treasure. If you need additional context to find a particular treasure, the video guide is especially helpful. Also see the Jupiter & Mars Walkthrough Strategy Guide or the Guide to all Creature Rescues.
